Oberheim Matrix-12 - Cass - Cassette Interface

The EXT T/7/will also respond to a footswitch such as
the Oberheim FS-7.
When set "+", EXT Tfl/will respond to a positive trigger
pulse (the rising edge of the pulse). When set"-", it will
look for a negative trigger pulse (the pulse's falling edge).
CASS CASSETTE INTERFACE
In addition to offloading your patches via MIDI, the MATRIX-12 also incorporates a
system that permits saving your patches to tape. The Cassette Interface feature of
the MATRIX-12 allows you to offload your SINGLE Patches, MULTI Patches and
the information in the MASTER PAGE (the Global data) onto standard cassette
tape. You may find that your creativity in programming new patches exceeds the
memory space (100 SINGLE Patches and 100 MULTI Patches) available. You may
also find it useful to save the MASTER PAGE - the information in CHAIN and
your MIDI settings - along with the Patches. The Cassette Interface makes it
possible to store your sounds on tape, programming a new set of Patches,
storing those and so on until you have a library of programs. We suggest that you
become familiar with the Cassette operation and learn to use it as you would any
other Sub-Page.
We also recommend that saving your programs to tape be done on a regular basis
anyway as a "back-up" in the event that one or more of your patches are edited or
erased accidentally or if a severe malfunction causes the MATRIX-12 to drop
memory. A back-up data tape should also be made before your MATRIX-12 is ever
serviced, for this reason.
What You Will Need
The MATRIX-12's Cassette Interface system was designed so that it would not be
necessary to invest a lot in tape recording equipment nor would it be required to
carry around a large, expensive stereo deck. Best results are obtained with using
a portable monophonic recorder or a computer data recorder. We have obtained
consistent results with the Radio Shack CCR-82 Computer Cassette Recorder
(Radio Shack part # 26-1209) although many others will work. When shopping for
a cassette machine, keep the following specifications in mind. Your cassette
recorder should have:
1. "Auxilliary" (AUX) or "Line" Input - Microphone (MIC) inputs may
worK but are not reliable.
2. Earphone, Headphone or 8-ohm External Speaker Output -
These outputs are able to drive the Cassette Interface circuitry easily.
Using a Line output is usually not reliable.
3. Playback Volume Control - It is extremely important to be able to
adjust the playback level of the data so that the MATRIX-12 is able to
recognize the information coming from tape. This is also why earphone,
headphone or external speaker outputs are necessary and a Line output is
not - the volume control is able to set the level of these outputs while Line
out remains steady and is not affected by the playback volume. On the
CCR-82, the pre-set playback volume "P" may be used.
